Even with the Meta Quest Pro, it only gets to about 24. The same goes for the HP reverb g2. For $1999, the Varjo Aero PCVR headset comes at 35 PPD, but at that price it doesn’t include the $3000 -$4000 PC to run it or the $600 base stations and controllers. It’s also wired to the PC
At $3000, i am guessing that the Apple headset will be 35 or higher PPD
Something must be off here. My 4k 40″ screen at 30 inches distance gives 70 ppd. It works well for reading, but I don't think it fits "retina quality". Retina would be above 100.
BTW, half of that (35ppd) would be an uncomfortable 1080p on 40″. Which makes Quest Pro even worse.
The only thing I think might make it better is that unlike on static screens head motion could add a nice smoothing effect to the picture, which might potentially lower the required PPD.
